A glow up of the original 3025 Technical Readout, the main body of this in-universe commemorative edition swaps out the original art with all new artwork in the style of modern day Battletech. This goes for not only the mechs but vehicles, aerospace fighters and even the dropships. The new Leopard artwork actually looks like something that could carry mechs.
The main text is exactly the same as the original. The new 'Appendix A' section, however, is where this book really shines. It attempts to rectify the in-universe mistakes between the original version, the 'Wolfnet' version, the removal of the 'Unseen' and everything else that has happened in the storied history of Battletech. It makes for some amusing reading and is a great bit of world building fiction.
